To ./ZZ 'whom t may concern: Y

Be it known that I, LOUIS JAENICHEN, va

citizen of the United States, and residing at Detroiuin the county of llVaynel and State of Michigan, have invented new and Improved Control Devices for Liquid Receptacles, of which the following is a specification.

This invention relates to means for so controlling the withdrawal of the Vcontents of fuel and other receptacles that a predetermined reserve will be left in the receptacles when the control members are in one posi-y tion and the entire contents may be withdrawn when the control members are in another position, and the object of this invention is to provide a control device of this character which shall be simple in construction, easily operated, and which may be used as a safety lock for the automobile on which a fuel receptacle of this character is mounted.

This invention consists, in combination with a receptacle and a suction connection attached thereto, of a suction tube slidable in said connection and having aclosed upper end and an aperture intermediate its ends opening into the suction connection, said connection being of such length that said aperture in the tube will be within said connection when the tube is in its normal position and when it extends to the bottom of the reserve liquid.

It further consists in key controlled means for preventing the introduction of a suction tube when that has been entirely withdrawn, so as to prevent unauthorized removal of the liquid from the receptacle.

It also consists in the details of construc tion illustrated in the accompanying drawing and particularly pointed out in the claims.

In the drawing, Fig. 1 is an elevation of a fuel tank equipped with my limproved control device. Fig. 2 is a central vertical section of this control device. Fig. 3 is a similar section of a modified forml thereof.

.tank 3 by screwing into said top, Vand a union 4 is adapted to receive a pipe 2 which extends thereQm .t0 theplace of consump- Vdrawn, this tion, for example, the engine vof the auto-'fi mobile if the tank is mounted on a'mot-or vehicle. Slidable verticallyfin this connec.k tion is a suction Vtube 5 which has :an "open lower end, a closed upper end' and an aperture 6 between its ends. The upper end may be-provided with a knob 7 if desired..l The suction connection 1 is so machined thatI the fit'around thetube at both the'top vand bottom of the connection is sufficiently air tight and vthe space between these ends and the connection is expanded so that'the tube is entirely free and out of contact with the connection.Vv As a result, a free and u-nobstructed passage exists at all times from the bottom of the tube 5 to the discharge union 1, no matter how far the tube is turned or moved up or down, so long as the aperture 6 thereindoes not pass out beyond thel ends of the connection.

I prefer to form a small groove 9 in the tube to receive the\spring pressed pin 10 mounted in the connection, which pin holds the tube in its normal upper' position. l/Vhile there, fuel may be drawn from the tank through this tube until a predetermined reserve only is left in the tank, the

stoppage of the flow of fuel warning the operator 1n charge that the lsupply is low; He thereupon forces down the tube 5 into the fuel reserve and again starts his engine v be replaced by a pin 12 mounted in a lock 13 which receives a key 14 whereby the pin 12 may be withdrawn to permit the tube 5 to be slid-down to normal position, the key being taken out when the tube is in normal position. When the tube is entirely withpin 12 is forced by--its spring into the path of the tube and thus prevents the introduction of this or a similar tube except when withdrawn by a key 14.'

The cap 16 may form an air tight joint with the hub 17 in which case the fit between the pipe 5 and the ends of the connectionvr may be quite loose, only sufcient vfriction being necessary to prevent theppe fromA sldnfgldotvn.
